To all 'whom it may concern.'

Be it known that we, VSTILLIAM LocKE, a citizen of the United States, and a resident of Westield, county of Union, State of New JerseyJ'nd ELIAS B. DUN'N, a. citizenof'the United Stat-es, and a resident of Est (range, county of Essex7 State of' New Jersey, have invented certain new and useful Improve- .ments in SuctionA paratusfor Pneumatic Cleaning Syst-ems, o which the following is u full,- clem", and complete disclosure.

The casing 1 is provided with a, Water inlet pi e 7 and a rain pipe .8, so that water may e supplied to the saturating chamber, and so that the contents of the chamber may be easil drawn off. The water flowing in throug the conduit 7 iillsthe v'chamber formed by the casing 1 lto a level correspondmg to that of the upper end of the conduit 6., and the water then flows into the conduit 6 and then downward into the'suctiona-paratus, tcgether with the dirt and air trat is mixed with the water.

with circular heads 1() 'and 11, which vare provided With suitable valves 12 for permitting .the escape of the mixture when under-coinpression. Communicating with the interior of thecylinder 9 through the valves 12 are external chambers 13'that are connected at their upper ends by the transverse passage 14 which passage terminates in a large outlet port 15. The connecting passage. 16 between the conduit 6 andthe interior cylinder 9 opens'into said cylinder at a point midway between itsv ends as indicated at 17. The

piston 18 is slightly shorter in length than one-half the length of the iston chamber 9.

The iston 18 within the cy inder 9 is slightly sma er in diameter than the internal diameter'of the 'said-cylinder, so that it ts `loosely Within the same and no packing is required,

except that'provided by thewater passing through the conduit 6 and the passagesli and 17.`A For this purpose theA piston 18 is provided with a series of grooves 19 thatgare adapted tobecome iilled or partly filled with water "and thereby .aid in forming .a packing for 'the-A said piston. vThe piston rod '20 are. provided withlputlets 23'fthatare closed passesthrough the head1() and through the outer casing 2 1 of one of the chambers '13 and is provided 'with a suitable stuffing box as indicated at 2.2L- The piston 1 of course may' b'eoperated' by-any suitable power apparatus',' s 'uc h as an engine or an 'electric mctorj- The 'chambers 13.'.a'nd the cylinder 9 bylf lsuitable-'plugs 0r Stoppers so -that said c ambersf-maygbe dr'air'ied` when desired.

When 'forrnj' of our invention is in operation, a lsuction is duit connected? 'waterdrtfand air,orldi'rt and air, are drawn 'throughthe chamber 1 and through the baffie-plate. 5 locatedtherein, thereby beconiin thoroughly. mixed with the water in' said produced within the conhthe inlet port 2 and chamber. The mixture then asses from thetop'' ci .said'charn er 1 into t e conduit 6 'pa Tages ."16'and 17 into the .ld -be noticedlthatlthe on' there'arside, as regards its-direction of motion, which vacuum increases until the rear end' ofthe piston passes the opening 17,

The suction apparatus. comprises a cylindrical casing 9 provided' -pistcrf 18j; when reciprocating the cylinder Y9, causes a vacuum to. be .produced through ie passages 6 and 16 in the manner above described. After the forward end ol' the piston 18 passesthe opening 17a lpressure is reduced in that portion of the cylin- 'by being forced out through the-adjacent valves 12 and into the corresponding chaf'mber 13, from which it passes into .the discharge conduit 15.

In the modification of the invention shown in Figs. 3 and 4 the construction of the pis.-

discharge passages is substantially ,the saine as that above described.l The saturating der9 and is formed by the casing 25 uponwhich the. cylinder 9 is mounted. 'lhecasing 25 forms a saturatin'g' chamber which is provided at its (',cntral portion with a transverse partition 26 having valves 27, similar to the valves 4, and is alsopr'ovided with a' battle-plate as indicated at 28. The opening 29 from the saturating chamber intb the interior of the cylinder 9-is located in a position similar to that oi the passage 17 referred to in the first modiiication. The

casing 25 is also provided with an inlet open ing 30 for permitting the inflow of air and dirt, or air, dirt and water; in a manner similar to that described in connection with the inlet port 2. The .piston 18 in the piston chamber 9 is also provided with the grooves 19 as indicated.V To insure thesaid grooves provide therequisite packing for the piston, a conduit 31 passes through the chamber 14 and enters'the cylinder S-at its central `aorticn as indicated. lWater is allowed to ilow through this conduit 31 and fills the grooves of the piston 18 at each recipfrocation,thereinlet and outlet pipes 32 and' 33 respectively so that water may be continually added to the chamber formed by the casing 25 if desi-redvand so. that .said chamber may be.. com- .pletely drained when necessary.

. Having now 'iarticularl'y described this form of our said1 and desire toprotcct by Letters lPatent is:

1.A lna pneumatic suction-cleanin f apparatus, the combination of a horizonte. piston chamber! a liquid saturating chamber at tached to the side of said piston chamber betweensaid piston chamberand the upper portion. of said saturating chamber .so as to level ofthe liquid in said sa'turatingchamber.

'2. .In Aa pneumatic suctionscleamn appatached to the side-'of said ypistoncllamber and a communicating passage entering said piston chamber intermediate its` ends `and being atall times filled with water soas to and a passage forming direct communication.

l at which point the vacuum then forcibly acts der in 'ront of the piston, the mixture thereton, the piston chamber and its adjacent chamber, however, is located below the cylinico of. Casing 2-5. is also provided with 'suitable invention, what we claim withdraw .the air and water from above the ratus the combination cfa horizonte piston y chamber, a' liquid' saturating. 'chamber atformingr direct communication between the upper portion of said piston chamber and said saturating chamber, so as t0 withdraw the air and water from above the level of the liquid in said saturating chamber.

3'. In a pneumatic suction-cleanin apparatus, the combination ol a horizonte piston chamber, a saturatingr chamber attached to the side of said piston chamber extending from the upper portion of the former, a passage from said saturating chamber to 'said piston chamber and openingr into the latter midway its ends, and outlet valves for discharging from said piston chamber.

4. In a pneumatic suction-cleaninif apparatus, the combination o1' a' horiz/.onta chamber, a saturatingchamber attached to the side of said piston chamber, a nassage from said vsaturating chamber extending?r from the upper portion of the 4former to said piston chamber and opening into the latter midway itsv ends, outlet valves for discharging from said piston chamber, and suitable valves coperating with said saturating chamber for preventing` the backflow therefrom int-o the inlet conduit.

5. In a pneumatic suction-cleaning,r apparatus, the combination of 4a horizontal piston chamber, a saturating chamber mounted adjacent thereto, a passage between the said piston chamber and forming discharge passages from the piston chamber, and a d1s- :1

charge conduit connected with said passages.

6. In a pneumatic suction cleaning apparatus, the combination of a piston chamber,

a saturating chamber mounted on one side of said piston chamber, a passage forminga ldirect'communication between said suctmn chamber and said piston ohamber, said passage extendin upward to a point adjacent the top of sai saturatin'gchamber, an inlet conduit communicating with the lower portion of said saturating chamber, and suitable valves for controlling the flow through said saturating chamber and said piston chamber.
